OPKs can't tell you that you've ovulated, only that you might soon. And while the average is that you'll generally ovulate 12-36 hours after first getting a positive OPK, that can vary greatly by person.

Temping is the best way of doing it. Most people set an alarm for a specific time so that they can temp, and then go back to sleep. My temp alarm is set for 5am; I'm awake for only a couple minutes and then I go back to bed.

I guess I haven't really done it because I didn't want to add anything else for me to obsess about. Seriously I'm only 4dpo and I couldn't stop myself from poas. Then expanded it, messed with colours and cntrasts and convinced myself I saw a line.....which I din't...just got line eyes. If nothing happens this cycle I guess it couldn't hurt to give it a go. Thanks for the input guys!
